As a time traveler, he unexpectedly possesses four skills: a musket in his left hand and a fire knife in his right hand. He can use powder barrels when encountering uneven roads and use precise barrage when he sees someone displeased. Soon, in less than twenty years, he unified a sea area and became the overlord of the North Sea that was feared throughout the continent. But one day—— He repeated his old tricks and returned to the coastal villages of the Holy Kingdom of Eman, intending to make more money before winter. However, he was repeatedly intercepted by the demons. Not only did he fail to make money, but he also almost lost his manpower. "The damn demons actually robbed me of my food!"
